How can the PHP code be modified to handle empty fields in the contact form without causing errors?

When handling empty fields in a contact form, you can check if the form fields are empty before processing the form data. This can be done by using conditional statements to validate each field and prevent errors from occurring. By adding a simple check for empty fields before processing the form data, you can ensure that the form submission is handled gracefully.

// Check if form fields are empty before processing
if (!empty($_POST['name']) && !empty($_POST['email']) && !empty($_POST['message'])) {
    // Process the form data
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    // Additional form processing code here
} else {
    // Handle empty fields error
    echo "Please fill out all required fields.";
}
